Solve using elimination ​

When you’re using elimination you eliminate using like terms so the -2y and +2y are set up to cancel each other out already, and after that since the y’s have been eliminated you can group together the rest of the like terms such as the X’s and non variable numbers, giving you 6x=-18 and after you simplify you end out with X=-3

The area of a square room can be expressed as 196x12y10z6 square feet . hajime is installing a wallpaper border along the perime
jeka94

The perimeter of the room will be 56x^6y^5z^3 feet

<h3>Area of a square</h3>

A square is quadrilateral with 4 sides. The formula for calculating the area of the shape is given as:

A = L²

Given the following parameters

A = 196x^{12}y^{10}z^6

Substitute

L²=196x^{12}y^{10}z^6
L=\sqrt{196x^{12}y^{10}z^6}\\L=14x^6y^5z^3

Determine the perimeter

Perimeter = 4L

Perimeter = 4(14x^6y^5z^3)

Perimeter = 56x^6y^5z^3

Hence the perimeter of the room will be 56x^6y^5z^3 feet

the volume V of a right circular cylinder of height 3 feet and radius r feet is V=V(r)=3(pi)(r^2). find the instantaneous rate o
Aleksandr-060686 [28]

When I see the words "instantaneous rate of change", I have to assume that you're in some stage of pre-calculus in your math class.

The instantaneous rate of change of a function is just its first derivative.

We have the function

                                   V(r) = 3 π r²

and we need its first derivative with respect to ' r '.  That shouldn't be
too hard, because the ' 3 π ' is nothing but constants.

Watch me while I do it slowly for you:

-- The derivative of  ' r² ' with respect to ' r ' is ' 2r '.

-- The derivative of V(r) with respect to ' r ' is  (3 π) times the derivative of  ' r² '.

-- The derivative of V(r) with respect to ' r ' is  (3 π) times (2r) =  <u>6 π r</u> .

The value of the derivative when r=3 is (6 π 3) = 18π = about <em>56.5 feet³/foot .</em>

sineoko [7]

Answer:

<h2>-2</h2>

Step-by-step explanation:

hello :

f(x)=-2x and g(x)=(1/2)^x

f(-2)=-2(-2) =4

g(-2)=(1/2)^-2 = 1/2^-2 = 2²=4
